Assorted Specialty Pliers (Retaining Ring Pliers and Hose Clamp Pliers)

The image displays two distinct types of specialized pliers, both likely constructed from steel or a similar robust metal alloy, exhibiting a metallic silver-grey finish with some darker areas indicative of wear or original coating. The tool on the left is a larger, more heavy-duty retaining ring pliers, possibly for internal snap rings, characterized by its wide, curved jaws with inward-pointing tips, designed to compress (or expand) a ring. It has a visible pivot point and what appears to be a spring-loaded or cam mechanism near the handles to maintain tension or position. The handles themselves are solid and slightly curved, showing some minor surface scratches and dulling of the finish consistent with regular use. There are visible rivets on the handles. The tool on the right is a smaller, more refined plier, likely a hose clamp plier or a specific type of clamping tool, designed to hold or compress. It features a unique jaw configuration with flat, slightly angled ends, and a visible spring mechanism between the handles to keep them open. The handles are partially covered with black, possibly plastic or rubber, grips which also show some wear and dullness. Markings are visible on the smaller plier's jaw area, reading "DIAMOND" and "USA", indicating the manufacturer and country of origin. Both tools appear to be in used but functional condition, displaying typical signs of professional or personal workshop use such as scuffs, minor abrasions, and some loss of original luster due to handling and age. Their construction suggests a practical design focused on durability and specific utility rather than aesthetic appeal, common for tools from the mid-20th century onwards.
